The Industry Requirement for 2D and 3D Inspection Technology in a Single AOI Platform

Technical Library | 2012-11-21 18:57:58.0

The continuing evolution toward advanced miniature packaging has led to ever increasing PCB density and complexity. As the manufacturing process becomes progressively more complicated, there is an ever increasing probability for defects to occur on finished PCB assemblies. For years the Automated Optical Inspection (AOI) industry has relied solely upon two-dimensional (2D) inspection principles to test the quality of workmanship on electronic assemblies. While advancements in conventional 2D optical inspection have made this technology suitable for detecting such defects as missing components, wrong components, proper component orientation, insufficient solder, and solder bridges; there is an inherent limitation in the ability to inspect for co-planarity of ultra-miniature chips, leaded device, BGA and LED packages.

Hand Soldering, Electrical Overstress, and Electrostatic Discharge

Technical Library | 1999-05-09 13:07:16.0

This paper will give the reader a general understanding of EOS and ESD phenomena. It specifically addresses hand soldering's role in EOS and ESD and how to protect against and test for potential problems. It discusses how Metcal Systems address EOS and ESD concerns and how they differ from conventional soldering systems.

Rework Challenges for Smart Phones and Tablets

Technical Library | 2015-04-23 18:48:18.0

Smart phones are complex, costly devices and therefore need to be reworked correctly the first time. In order to meet the ever-growing demand for performance, the complexity of mobile devices has increased immensely, with more than a 70% greater number of packages now found inside of them than just a few years ago. For instance, 1080P HD camera and video capabilities are now available on most high end smart phones or tablet computers, making their production more elaborate and expensive. The printed circuit boards for these devices are no longer considered disposable goods, and their bill of materials start from $150.00, with higher end smart phones going up to $238.00, and tablets well over $300.00.

Combination of Spray and Soak Improves Cleaning under Bottom Terminations

Technical Library | 2014-10-23 18:10:10.0

The functional reliability of electronic circuits determines the overall reliability of the product in which the final products are used. Market forces including more functionality in smaller components, no-clean lead-free solder technologies, competitive forces and automated assembly create process challenges. Cleanliness under the bottom terminations must be maintained in harsh environments. Residues under components can attract moisture and lead to leakage currents and the potential for electrochemical migration (...) The purpose of this research study is to evaluate innovative spray and soak methods for removing low residue flux residues and thoroughly rinsing under Bottom Termination and Leadless Components

Graphene electronic fibres with touch-sensing and light emitting functionalities for smart textiles

Technical Library | 2019-08-29 13:04:55.0

The true integration of electronics into textiles requires the fabrication of devices directly on the fibre itself using high-performance materials that allow seamless incorporation into fabrics. Woven electronics and opto-electronics, attained by intertwined fibres with complementary functions are the emerging and most ambitious technological and scientific frontier. Here we demonstrate graphene-enabled functional devices directly fabricated on textile fibres and attained by weaving graphene electronic fibres in a fabric. Capacitive touch-sensors and light-emitting devices were produced using a roll-to-roll-compatible patterning technique, opening new avenues for woven textile electronics. Finally, the demonstration of fabric-enabled pixels for displays and position sensitive functions is a gateway for novel electronic skin, wearable electronic and smart textile applications.

Testing Printed Circuit Boards for Creep Corrosion in Flowers of Sulfur Chamber

Technical Library | 2015-07-16 17:24:23.0

Qualification of electronic hardware from a corrosion resistance standpoint has traditionally relied on stressing the hardware in a variety of environments. Before the development of tests based on mixed flowing gas (MFG), hardware was typically exposed to temperature-humidity cycling. In the pre-1980s era, component feature sizes were relatively large. Corrosion, while it did occur, did not in general degrade reliability. There were rare instances of the data center environments releasing corrosive gases and corroding hardware. One that got a lot of publicity was the corrosion by sulfur-bearing gases given off by data center carpeting. More often, corrosion was due to corrosive flux residues left on as-manufactured printed circuit boards (PCBs) that led to ion migration induced electrical shorting. Ion migration induced failures also occurred inside the PCBs due to poor laminate quality and moisture trapped in the laminate layers.

Development of a Design & Manufacturing Environment for Reliable and Cost- Effective PCB Embedding Technology

Technical Library | 2011-10-06 13:59:04.0

The desire to have more functionality into increasingly smaller size end products has been pushing the PCB and IC Packaging industry towards High Density Interconnect (HDI) and 3D Packaging (stacked dies, embedded packaged components). Many companies in the high-end consumer electronics market place have been embedding passive chip components on inner PCB and IC Packages for a few years now. However, embedding packaged components on inner layers has remained elusive for the broader market due to lack of proper design tools and high cost of embedding components on inner layers (...) This paper will highlight several key industrialization aspects addressed in the frame of the European funded FP7 HERMES* project to build a manufacturing environment for products with embedded components. The program entered its third year and is now dealing with the manufacturing of functional demonstrators as an introduction to industrialization.

Assembly and Reliability of 1704 I/O FCBGA and FPBGAs

Technical Library | 2013-03-14 17:19:28.0

Commercial-off-the-shelf ball/column grid array packaging (COTS BGA/CGA) technologies in high reliability versions are now being considered for use in a number of National Aeronautics and Space Administration (NASA) electronic systems. Understanding the process and quality assurance (QA) indicators for reliability are important for low-risk insertion of these advanced electronic packages. This talk briefly discusses an overview of packaging trends for area array packages from wire bond to flip-chip ball grid array (FCBGA) as well as column grid array (CGA). It then presents test data including manufacturing and assembly board-level reliability for FCBGA packages with 1704 I/Os and 1-mm pitch, fine pitch BGA (FPBGA) with 432 I/Os and 0.4-mm pitch, and PBGA with 676 I/Os and 1.0-mm pitch packages. First published in the 2012 IPC APEX EXPO technical conference proceedings.

Printed Circuit Board Tracking with RFID: Speed, Efficiency and Productivity Made Simple.

Technical Library | 2008-05-07 17:54:58.0

Tracking goods through manufacturing was originally accomplished with pencil, paper and human input. Barcodes introduced an automated, machine-readable tracking mechanism that streamlined all types of manufacturing. But modern printed circuit board (PCB) assemblies are running into limitations because of barcode labels. And though barcodes and RFID tags will co-exist, the relatively large barcode labels have to find increasingly scarce real estate on high density boards.
